Abstract
Several embodiments of direct injected spark ignited internal combustion engines. In these embodiments, the fuel injector is positioned quite close to the cylinder bore axis so as to ensure a homogeneous mixture in the combustion chamber under all running conditions and particularly high speed high load conditions. The injector in each embodiment is positioned, however, relative to this spark plug or plugs so that fuel will not be sprayed into their gap to cause fouling. In addition, an improved arrangement for showing heat transfer from both the spark plugs and fuel injectors to the engine coolant is also disclosed.
